The aims of the present study, were a) to investigate physiological responses in man who ingested branched-chain amino acid (BCAA) drink for 8 consecutive days during and after incremental exercise and b) to examine the effects of BCAA drink intake on aerobic performance during the exercise. Five healthy males ingested 2000mg・day^<-1> of BCAA drink for 7 consecutive days and 10000-mg BCAA before the experiment and performed incremental cycle ergometer exercise until exhaustion. Exercise duration until exhaustion significantly extended and blood lactate concentration at a 100-W load significantly decreased compared to before ingesting BCAA (p<0.05, respectively). These results suggest that BCAA drink intake could result in improving aerobic performance.
